Abstract
A fluid pressurization apparatus utilizing a slanted cam disk to oscillate, or to oscillate and rotate a set of piston assemblies arranged in a circle. The motion of the pistons is utilized to pressurize fluid or to perform work. The piston assemblies have multiple elements configured to allow the plungers to be engaged or disengaged to the motion of a disk by manipulating a working fluid introduced into the apparatus. By virtue of these disengageable plungers, the apparatus can be disabled and resumed at will. This apparatus is particularly well suited for pressurizing liquids such as water for high-pressure and high-flow applications.
